Abstract (en)
[origin: WO2019229352A1] The invention relates to an air compressor comprising a centrifuge-type compression wheel defining an axial direction (DA) and a radial direction (DR), an air admission opening extending circumferentially around the compression wheel and opening up onto a compression piece (150), the compression piece (150) comprising a first part (151) forming a volute (152) for the ejection of compressed air which is mounted facing the compression wheel in the radial direction (DR), and an at least partially annular second part (153) extending around the first part (151), the second part (153) comprising a central opening (156) receiving at least part of the compression wheel and an air deviation torus (154), the volute (152) consisting of a metal material and the torus (154) consisting of a thermoplastic material loaded with non-metal elements, the thermal expansion of the thermoplastic material corresponding to that of the metal material.
